Lagoona Blue is a 2010/2016-introduced and all-around character. She and her younger siblings, (Kelpie, Dewey, Squirt, Tad and Ebbie), are an unusual kind of sea monster, as they are the offspring of a sea monster and an ocean nymph. Lagoona is a student at Monster High, having come all the way from the Great Scarrier Reef to expand her horizons. And she's done so admirably. If there is one person in the entire school who could befriend anyone, it's Lagoona. She is patient, kind, and considerate, but does not sugarcoat her message or allows anyone to walk over her.

She gives him leeway beyond her standards despite the harm it does her because she is aware that his home situation is far from ideal. She is not happy with the situation, but she knows she would also not be happy without him.
